Qualityisthe lifeofanenterprise,andinnovationisthesoul ofanenterprise

In1933,the British IClcompany first discovered polyethylene (PE),which has since been developed ntoa seriesofresins with various structures and properties produced byvarious processes.Itaccounts forone-third ofthe world's syntheticresinproduction,rankingfirst.Today,plastic pipesareno longer mistaken bypeopleas a"cheapsubstitute"formetal pipes.Among them,polyethylenepipesare highly favoreddue totheirsuperior performance and wide application,especially in gas transportation.

Agood pipeline should notonly have good economy,butalso ensureaseries ofadvantages suchas stable and reliable system interface,impact resistance,crack resistance,aging resistance,corrosion resistance,etc. Compared with traditional pipes,PE pipe system has the following series of advantages:

Reliableconnection

Thepolyethylenepipelinesystemisconnectedbyelectricmelting,andthestrengthof thejointishigherthanthatof thepipelinebody;Thepolyethylenepipelineisconnected tootherpipelines using flanges,which isconvenientand fast.

Good thermal impact resistance

Polyethylene hasan extremely low low-temperature brittleness temperatureand canbe safely used within - 6 0 - 4 0 ^ { \circ } C # During winterconstruction,due tothegood impact resistanceofthematerials,therewillbenooccurrenceof pipe brittleness.

Good crack resistance

PEhaslownotchsensitivityhighshearstrength,andexcellentscratchresistance,withoutstandingresistance toenvironmental stress cracking

Good chemical corrosion resistance

PEpipescanwithstand corrosionfromvariouschemical media,and thechemicals presentinthesoil willnotcause anydegradationofthepipelinematerial.Polyethyleneisanelectricalinsulator,soitwilnotrot,rust,orundergo electrochemical corrosion;Furthermore,itdoes notpromote thegrowthofalgae,bacteria,or fungi.

Flexible TypeDesign

Theflexiblityof PEpipes makes themeasy tobend,andinengineering,theycan bypass obstaclesby changing the direction of the pipe.In many cases,the flexibility of the pipecan reduce the amount of pipefitings and lower installation costs.

Aging resistance

Polyethylene pipes containing 2 - 2 . 5 % uniformly distributed carbon black can be stored outdoors or used for 50 years without being damagedby ultraviolet radiation.

Goodwear resistance

Comparative testsonthewearresistanceof PEpipesand steelpipes show that the wearresistanceofPEpipesis fourtimesthatofsteelpipes.Inthefieldofmudtransportation,comparedwithsteelpipes,PEpipes havebetterwear resistance,which means that PE pipes havea longer service life and beter economy.

Lowwaterflowresistance

PEpipes haveasmooth innersurfacewitha Manning'scoeffcientofO0.O09.The smooth surfaceand nonadhesive propertiesensurethatPEpipes havehighertransportcapacitythantradionalpipes,whilealsoreducingpressre loss and energy consumption during transportation.

Easy to transport

PEpipesarelighter thanconcretepipes,galvanized pipes,andsteelpipes,making themeasiertotransportand install.Lower laborand equipment requirements mean lower installation costs for the project.

Multiple construction methods

PE pipelines have multiple construction techniques.Inaddition to traditional excavation methods,various non excavation techniquessuchas directionaldrling,lining,cracking,and jacking canalso beusedforconstruction. Thisistheonlychoiceforplaceswhereexcavationisnotalowed,soPEpipelineshaveawiderrangeofapplications.

Cost-effective

The priceofPEpipes iscomparabletothatofballmilledfitings.Considering thelongservice lifeand convenient constructionofPE pipes,the overall cost is lower.

Due to its series of advantages,PE pipes can be widely used in the following fields:

·Urbanwater supply

Due to itsadvantages ofsafety,hygiene,and easeof construction,PE pipesare an ideal material for urban water supply.

Natural gas and gas transmission pipelines

Due toaseries of advantages such as reliable connection,stable performance,easy construction, and corrosionresistance,PEpipelines have become theonly choice formediumand lowpressure natural gas transmission pipelines.

Foodandchemical industries

PE pipes have unique chemical corrosion resistance and can be used for the transportation or dischargeof variousacid-base salt solutions.They havea longservice lifeand low cost and maintenanceexpenses.

StrictManagement and Science Testing

Transportation of mineral sand and mud

The wear resistance of PE pipes is four times that of steel pipes,and they can be widely used to transport flyash frommines,power plants,and mud for river dredging.

·Replace cement pipes,cast iron pipes,and steel pipes

Fortherenovation of existing cement pipes,castiron pipes,etc.in the city,PE pipes can be directly inserted into theold pipes for replacement without extensive excavation.The project cost is lowand theconstruction timeisshort,making itparticularlysuitable forpipelinerenovation inold urbanareas.

· Landscape greening pipeline network

Landscape greening requires a large number of water pipelines,and PE pipelines are low-cost and worth promoting vigorously.
